LANTERN.

SPECIFICATION forming part of Letters Patent No. 394,025, dated December4, 1888.

Application tiled November 19, 1887i Serial No. 255,643. (No model.)

.T0 all whom, t may concern.'

Be it known that we, FRANK REGINALD SMITH and ADDISON PINE() SMITH,citizens of the United States, residing` at Houlton, in the county ofAroostook and State of Maine, have invented a new and useful Improvementin Lanterns, ot which the following is a specitlcation.

This invention relates to tubular lanterns in which the globe is mountedin a `globe- 'rame which is attached to the sides ot' the main trame insuch manner that the globe and its supporting-frame may be raised whenit is desired to expose the burner-cone for trimming, lighting,extinguishing, or otherwise.A

The object ot this invention is the production of a tubular lantern inwhich the frame that carries the globe when in an elevated position,for' the purpose of giving free access to the burner tor trimming,lighting, extinguishing, or the like, will remain so, and will not dropback until forced down over the burner.

The invention consists in the novel combination and arrangement of theparts, hereinafter fully described, illustrated in the accompanying'drawings, and pointed out in the claim hereto appended.

In the accompanying drawings, forming part of this speciiication, and inwhich like letters of reference designate corresponding parts, Figure la perspective view ot' a tubular lantern embodying my improvements inwhat I deem their best form, the parts being in position for use. Fig. 2is a similar view of the same with the globe in an elevated position inorder to afford access to the burner for trimming', lighting,extinguishing, or otherwise. Fig. 3 is a side elevation ot' the tubularlantern, the globe being removed and the perforated plate tilted, as forthe insertion of a new globe.

In the drawings, A designates the reservoircap, B the burner and C C theinclined tubes which conduct air to the burner, and D is the verticaltube, which is a rigid dependent portion of the top of the main trame,all of a construction too well known to require description in detail.

The globe-cap E, as heretofore, is adapted to slide upon the verticaltube D, and is provided upon its under side with a ring-shaped catch,which embraces the upper end of the globe. This ring-shaped catch F ispreterably composed ot` a single piece ot wire bent into circular formand having the two ends meeting closely together and securedby solderingor otherwise to the rear ot the globecap E. Intermediately of the endsof this piece ot wire composing the ring-shaped catch is formed athumb-piece, f, formed by bending up the central portion ot' the wireinto two parallel parts, which thumb-piece passes through an opening, e,in the globe-cap E, and enables the ring-shaped catch to be raised, whenit is desired to release the top ot the globe to remove it or for theinsertion of a globe. Upon the upper side of the globe is provided apiece ot' fiat spring metal, G, which is secured thereto by soldering orsimilar means. The top of this piece of spring metal G is bent at rightangles to its length and forms a locking projection, o2, which, when theglobe-cap is down at the bottom of the vertical tube D, engages ashoulder, d, consisting ot' a piece of metal, preferably wire, securedin a suitable manner to the vertical tube D. At the t' ree end ot thispiece of spring metal G is iixed a small knob or handle, by which thespring may be made to disengage the shoulder d on the vertical tube topermit the sliding frame to be elevated, the normal position otl thespring being against the vertical tube D. This spring G on the upperside of the globe-ca p E, together with the small shoulder d on thevertical tube, constitutes a locking device, whereby the slidingglobeframe may be securely retained in a depressed position.

The globe-trame consists ot' the bottom portion, h2, and the side wires,71 71, which are mounted in guides 7L 7i. and extend along the inclinedsides C C of the main frame to the globe-cap, to which they are secured.Then constructed with reference to economy, durability, and strength,this entire frameismade of a single piece of wire, the ends, as beforestated, being ixed to the globe-cap. The bottom portion, h2, of theglobe-frame is bent into semicircular form and passes around one side ofthe burner-cone.

The globe-seat I,which surrounds the burner- IOO cone, is preferablyperforated, and is hinged,

y one end of which is attached to the globe-seat,

so that when the sliding globe-frame is in its lowest position thespring K is compressed, the tendency of which is to force one side ofthe globe-'seat upward, when the top of the globe is released from theglobe-frame, thereby causing the globe-seat to turn on its hinge; butwhen the top of the globe is notreleased from the globe -frame thetendency of the spring K is to force the globe-frame upward and make thesaid f 1ame slide in the guides h The operation is as follows: When itisdesired to insert the globe, the bottom of it is placed upon theperforated globe-seat I, which is (when there is no globe in the lanternand the seat in its lowest position) always in an inclined position. Asthe globe isbrought to a Vertical position, the ring-shaped catch F israised by the thumb-piece f and the top of the globe slipped under it.The ring-shaped catch, being then released, descends and fits snuglyaround the top of the globe and holds it securely in position. Thespiral spring K aids in retaining the globe in the globe-frame byexerting a constant pressure upon the globeseat and keeping it incontact with the bottom of the globe. In order to remove the globe fromthe lantern, it is only necessary to raise the ring-shaped catch by the.thumbpiece and tilt the globe. X/Vhen it is desired to elevate theglobe-frame in order to afford free access to the burner B fortriniiming, lighting, extinguishing, or other purpose, the spring G, bythe knob or handle at its free end, is released from engagement withtheV shoulder d of the vertical tube D. The spiral spring K, being thenin a depressed condition, instantly acts upon the globe-seat I andforces the sliding globe-frame upward, making it slide in the guides hand assume a position above the burner, as is shown in Fig. 2, and theresupports it until forced down again. The spring G, when the globe isforced down upon the burner B, engages the shoulder d of the verticaltube I) and Iirmly locks the globe down and prevents it rising from itsdepressed position.

I-Iaying thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In a tubular lantern, the combination of a globe-seat, the slidingglobe-frame, said seat and frame being hinged together, as shown, and anincased coiled spring bearing against the under side of the globe-seatopposite the point where the said seat is hinged to the slidingglobe-frame, whereby the globe-seat is automatically tilted,substantially as described.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in presence of two witnesses.
